Molecule Structure Image



Cyclopentane is a highly flammable alicyclic hydrocarbon, consisting of a ring of five carbon atoms each bonded with two hydrogen atoms above and below the plane. It is used in the manufacture of synthetic resins and rubber adhesives and also as a blowing agent in the manufacture of polyurethane insulating foam, as found in many domestic appliances such as refrigerators and freezers, replacing environmentally damaging alternatives such as CFC-11 and HCFC-141b. More advanced technologies, such as computer hard drives and outerspace equipment employ multiply alkylated cyclopentane (MAC) lubricants because of their extremely low volatility.
